This particular breed of Puffer has been heavily mutated by exposure to Phazon, giving it strange new abilities. As it flies, it searches the area for Phazon energy to consume. The Puffer will absorb this energy out of any nearby bioform and energize itself. The Puffer will then use the energy to fire a powerful attack back at their target. This ability comes with a price--the Phazon energy comprising their body is rather unstable and easily disrupted by any type of weapon fire.
